Replicating production on your laptop using the magic of containers

Containers are an amazing technology that are revolutionising how we deploy and create applications. Docker and Kubernetes are helping developers and organisations realise the magical potential that container technology and orchestration offer. Enter MicroShed and the Testcontainers framework enabling local test automation that leverages that magical portability containers offer. In this session we'll explore how Testcontainers can help you run and test with true-to-production environments in development with minimal re-writing of your test code.

Write tests that spark flow

Sebastian Daschner (IBM)

For most enterprise projects, testing is not really fun. It’s boring, cumbersome, and takes time and effort — especially for distributed applications or when changes in existing functionality forces test scenarios to adapt. Still, software tests are crucial; so, how can we tackle them in an effective and productive way?

Testing practices of database communication in open-source projects

Csaba Nagy (Software Institute - USI, Lugano)

Database communication has a distinctive role in the codebase. We have to deal with libraries dedicated to specific databases, and we often use query languages such as SQL. It is tempting to avoid touching such code, and when it comes to testing, we face many challenges. To mention only a few examples: Will we mock or use an in-memory database? Do we need to write an integration test or a unit test? How do we know which code is responsible for database communication?

Extreme learning situations as testers - How to add value while you're still learning

Christian Baumann (Finologee SA)

As software testers, we accept that each new role will require us to learn new technologies and skills. We also know that we often feel the need (or are told of the need) to provide value to the project quickly. Both of these competing expectations are normal to a certain degree. When I joined a new project about testing an API against a European Union standard for payment services, I had to do both to an extreme I had never experienced before.

Testers are from Mars, developers are from Venus

Huib Schoots (De Agile Testers)

Subtitle: what every developer should know about testing and testers

Testers and developers sometimes seem to be like creatures from different planets. Recognize these? Developers can't test. Testers can't code. Testers make the life of a developer miserable. Developers never test their own stuff. Testers can't keep up because testing is too slow, etc.

Will it blend? Java agents and OSGi

Robert Munteanu (Adobe)

Java agents are a little-known but extremely powerful part of the Java ecosystem. Agents are able to transform existing classes at runtime, allowing scenarios such as logging and monitoring, hot reload or gathering code coverage. However, their usage presents a number of pitfalls as well.

Cognitive Testing: Imparting Intelligence to a test environment

Geetha Karna (IBM)

Cognitive testing is a modern testing technique in this fast changing and dynamic technology world . The erstwhile testing arena is making a shift towards quality engineering, and testing is intended to become more iterative, progressive, Intelligent , contextual and seamlessly integrate with development.

Make testing Enterprise Java more joyful

Sebastian Daschner (IBM)

Testing is still a topic that most developers would like to avoid. Even though it is crucial for working software, developing and maintaining tests takes certain time and effort — especially for distributed applications or when changes in existing functionality forces test scenarios to adapt. Omitting software tests can’t be the solution; therefore, how can we tackle enterprise tests in an effective and productive way?

CI systems need care, too! Here's how we improved ours over the years

Tobias Geyer

When I started at my current employer five years ago the CI system consisted of an outdated Jenkins installation on a PC which was located under the desk of a developer. Builds were triggered three times a day, so a developer had to wait multiple hours after a commit until the feedback arrived. The builds couldn’t be reproduced locally, so debugging was at times done via console logging on the CI system.

Using sensors to reduce wasted support time: a case study for testing in IoT

Tim Winselmann (BREDEX GmbH)

A well-designed and tested IoT product should successfully help customers save money based on the information the system produces – but what can that look like for a real customer, and how can testing be done in the project?

In this talk, I will present a case study for a customer who produces metal-pressing machines for the can industry. The customer’s aim is to reduce unnecessary support visits to production sites: by measuring various parameters of the machine, they can determine whether the support case may have been caused e.g. by changing the thickness of the metal.
